To Il whom il muy concern:

le it known that l. WILLIE HEAPQa citizen of the lfnited States oiAmerica'.`residing at Muskegon. in the county of Muskegon and State ol' Michigan. have invented certain new and useful improvements in Floats for Flushing-Tanks. ol' which the'following is a specilin u cat-ion. reference being had therein to the accompany-A ing drawings.

The invention relates to lloats more particularly designed for use in connection with flushing tanks. and

the invention'consists in the novel construction of the Il is an elevation ofthe operating connection for this valvc: and Fig. -l is a section through the connection to the tloat controlling the water inlet valve.

in the present. state of the art. floats for controlling the valves of a liushing tank and for similar uses. are

-f .gtfnerttlly' formed of sheet metal having soldered .joints ln many places where these floats are used. the water contains impurities. causing the rapid corrosion of the metal or the setting-up of galvanic action between the niet-al ol' the float and the solder'. resulting in rapid deterioration; eventually` the float becomes pervious to water and lills. rendering the same useless.

lt is oneof the objects of the present invention to form the float of a material which is impervious to water and will not be affected chemically b vjany of the impurities Acontained therein. It is a further object to provide connections between the float and valve in which solder not employed. These objects I preferably attain bv forming the lioat of glass and providing it with an integral nipple.'to which the operating connection may be attached without the use of solder.v

As shown in Fig. l.. A is the .float for controlling the water inlet valve. lhis is preferably of spherical form. which may bc blown or otherwise fashioned and which is provided with a neck or nipple B having external yscre-w-threads C fornied thereon. D is the rod connecting the float to the'inlet value E. The end of this rod provided witha cap l. which is threaded correspondinglly to the nipple il and adapted to be engaged therewith. lhus the lio-at may be quickly attached or roinoved iront its connection. i

The valvc controlling the outlet is of the usual type ot' llo-tt valves designed for this purpose and has a bell- 'shaped lioat (fr formed of glass. This float is also provided with an integral threaded nipple H, which is arranged at the. upper end thereof and isv closed t0 prevent passage of water in to the float. The lower portion of the bell is provided with an annular groove l. lin

which a suitable gasket .lis placed for forming the valve face. and below this is a contracted port-ion K 0i the -bell which is also threaded to. engage theiguide cap L. This guide cap is formed of metal and is providetlwvith a'sleeve M which [its overa central guide'post N. pro-v jecting upward from the fit-ting O -r'ortning the-valve seat. This valve is operated in the usual way by lifting from its seat as by an operating lever P and `connecting link Q. after which the float will hold thevvalve open until the tank is empty. The bell G is guided in its movement by the sleeve M which loosely engages the post N and to further limitthe amount of lateral movement possible. preferably employ a link Q oi the following construction ;--a. is a threaded cap for engaging the nipple H on the bell. which has rigidly connected therewith the rod or wir-eb. bent at c to form a shoulder or stop and thenextending upward. At its upper end this wire is bent into a round loop d. e is a separate section of the link which is detachably secured to the lever P. as by the threaded hook f and thumb nut g. It is a bent portion in the member `c which `forms a stop and at thelower end of said member is a loop or eye i which engages the member b below the-stop With this construction. the necessary lost motion is provided by the sliding of the member e in relation to the niember b to perniit of the lever P being returned before the loat is lowered to its seat. At the saine time.V the eircular loop d. surrounding the member e. 'liinits the amount of lateral movement permitted between-the members b e, so as t'o prevent any binding ol' the sleeve M upon the post N.

W hat 'I claim as my invention iszl'. A oat formed of afbell of glass closed at one end and open at the other. an externally threaded nipple on the upper portion und integral therewith, an operating connection and an internally threaded cap carried thereby for engagement with said nipple.

i. In a oat valve, a tioat formed of a bell of glass, fashioned to have a closed nipple at one end and threaded at its opposite end and a guide cap engaging' said-threaded end. f

In a fioat'valve, a float formed of a bell of glass, having.y an open neck at its lower end of reduced diameter, an annular valve face of greater diameter above said reduced portion and a cap engaging said reduced portion provided with a guide sleeve. A

4. In a float valve. a valve seat having a guide pin projecting upward centrality thereatbove, a float.' valve closed at its upper end and havinga guide sleeve at its lower end lifting about. said guide pi, u lever for lifting said oat, a two-part link connecting said lever to said iioat, one section thereof provided with am oye orloop surrounding the 'lrvulur loop slil'rounrlinf."A l'hl inst-named sortion, whel'lry :L limited universal movvmenf is permitted,

A float vulve comprising' :1 hollow glassy: body having :t hollow noch or nipple' integral therewith and externally` threaded, and n mp Col'l'osnouflingly threaded find engaging' smid nipple.

li. A float vulve comprising a hollow glass body having? :1n-open omlorl llmfk or nipple and :l rap fxlornnlly engagin; said novk or nipple.
